Load / Elongation curves: Mooring Line

Load / Elongation curves of “used” Mooring Line.
Used“ means after average usage under normal weather conditions and is simulated in the lab with 10 loadings at 20% of the break load.

The length of a vessel has proven to be the most useful reference for the sizing of mooring lines. Rope diameters mentioned are average figures which result from past experience. Deviations for particular vessel designs are likely to occur. The rope sizes are valid for a classic mooring layout: one headline, one sternline and two springs. A rule-of-thumb for the dimensioning of Polyester and Polyamide mooring lines is length of vessel in metres + 2 = rope diameter in mm. Size for ease of handling should also be considered. For larger vessels please contact our sales and technical specialists for advice. For super yachts, the respective classification requirements must usually be followed.
